The DBH 8878 is a radial shaft seal designed to keep lubricants in and contaminants out on rotating shafts. With a 25 mm shaft, 40 mm housing, and 10 mm height, it fits small to medium gearboxes, pumps, and electric motors. MR Industrial Accessories LLC supplies it as part of our seal line, with technical support to help you select the right seal.
This DBH radial shaft seal carries part number 8878. It features a single lip with spring (Lx design) to retain lubricant in one direction while blocking dirt. The elastomer lip and metal case provide flexibility and rigidity for press-fit installation.
Common applications include input/output shafts on reducers, centrifugal pumps, electric motors, compressors, and transmission equipment. It's also used in agricultural machinery, conveyors, and process equipment where bearings and gears need protection. Check the shaft for wear or scratches before installation to maximize seal life.
For installation, clean the housing and shaft, lubricate the lip with the equipment's grease or oil, and press the seal in square without side impact. If the shaft has a groove or burr, consider a wear sleeve. Selection depends on speed, temperature, and lubricant; let us know those parameters to confirm the 8878 or suggest a different lip or material.
To request a quote, send the part number 8878 by WhatsApp or email. Include shaft, housing, and height dimensions, plus a photo of the old seal if possible. We'll search our seal line for the best match and advise on lip design and material based on your fluid and temperature.
If you need an equivalent for critical equipment, share the operating context and we'll help you choose. Our team responds promptly to quote requests and can suggest alternatives.
